That won't do any much because only the link at the tab can still provide sounds but not in the comments. So, it cannot work if you do that, that would be a waste of time.
WHEN YOU ADD GIFS WITH SOUND TO THE COMMENTS WITH THE ADD IMAGE BUTTON, THERE IS NO SOUND. I THINK WHEN WE ADD ONE OF THOSE SOUNDY GIFS TO THE COMMENT, THERE SHOULD BE A SOUND BUTTON NEXT TO THE COMMENT.
